SPRINGFIELD - Sixteen Acres neighborhood residents report that a number of their vehicles were broken into early Saturday morning.

Mohawk Drive resident Karen Powell said she learned of the break-ins at about 4 a.m. when a neighbor called to report that her car doors were open.

“It was pretty fast and pretty unnerving,” said Powell, adding that she lost a small amount of change, but, oddly enough, not all the change that had been in her car.

A neighbor, Robb Carty, who lives on the same street, was harder hit. He said lost some $400 or more in gift cards, CDs, a cell phone charger, a pair of prescription sunglasses - even the registration for his truck.

“They are having a field day,” Carty said. “They are very fast, very smooth.”

Powell and Carty said they routinely lock their vehicles “They must have used a shim to get in," Carty said.

Powell said a neighbor across the street who also got hit, believed that she too had locked her car the night before. “She always locks her doors,” Powell said, adding that her neighbor’s car beeps when locked or unlocked remotely and “nobody heard a noise.”

Powell said she knows of at least five others in the neighborhood who had items stolen from their vehicles and that anecdotal evidence suggests that a number of others may have been hit as well.

“It’s a shame because our neighborhood is very nice,” Carty said.

Carty said he heard reports residents in the South Branch Parkway area were similarly hit a week or so ago.

Springfield police detectives investigating the break-ins could not be immediately reached for comment.
